Specification of Letters Patent.

Patented NOV. 2, 1909.

Application filed March 15, 1909. Serial No. 483,391.

To all whom it may concern:

Be it knownthat I, JOHN L. MUNsILL, a citizen of the United States,residing at Leavenworth, in the county of Leavenworth and State ofKansas, have invented certain new and useful lmprovements in Tongs, ofwhich the following is a specifica-tion.

My invention relates to improvements in tongs, and my object is toprovide a pair of tongs especially adapted for handling large panes ofplate-glass.

By employing my tongs a large pane of plate-glass can be carried to awindow-frame and placed in position more easily and safely by a lessnumber of men than has been possible heretofore, on account of the easewith which a reliable grip can be obtained on the glass with the tongs.

In order that the invention may be fully understood, reference will nowbe made to the accompanying drawing, in which:

Figure 1 shows a front elevation of the tongs gripping a piece ofplate-glass. Fig. 2 is a rear elevation of the tongs. Figs. 3 and 4 arebroken detail rear and side elevations, respectively, of one of thehandles forming part of the tongs. Fig. 5 is a cross section on line V-Vof Fig. 1, with the glass removed. Fig. 6 is a longitudinal sectionalview through one of the jaws forming part of the invention.

In carrying out the invention, I employ a pair of crossed levers 1 and2, provided at their lower ends with ingers 3 and 4, respectively,extending at an angle to the levers, so that when the latter areoperably connected, as shown in Fig. 2, finger 3 will extend beneathlever 1, while finger 4 will extend beneath lever 2. This arrangementinsures the opening and closing with the levers of a pair of jawshereinafter described.

Lever 1 is provided near its lower end with an enlarged circular,recessed portion 5, in which the enlarged portion 6 of lever 2 snuglyand operably fits, said enlarged portion 6 being held in place by a pairof retaining-plates 7 riveted or otherwise secured to lever 1 and itsfinger 3, and retaining-plates 7 a secured to lever 2 and its finger 4.The levers are further connected by a rivet 7b, although when the latteris employed the retaining-plates may be dispensed with, and when theretaining-plates are used the rivet may be omitted, if desired. Levers 1and 2 are provided at their upper ends with laterally extending mainhandles 8 and 9, and at their intermediate portions with laterallyextending supplemental handles 10 and 11, respectively, the supplementalhandles being arranged at different elevations for a purpose which willhereinafter appear.

Fingers 3 and 4 are provided at their lower ends with laterally orforwardly projecting studs 12 and 13, upon which the jaws 14 (abovereferred to) are pivotally mounted, so that the levers may swing freelyand laterally independently of the jaws. Jaws 14 are held in position onthe studs by retaining-nuts 15, which screw against shoulders 16 withwhich the studs are provided to prevent the nuts from binding againstthe jaws 14, and thus preventing them from moving freely on the studs.The studs are also provided with shoulders 17, to prevent the jaws fromcontacting with the retainingplate 7. The jaws are, preferably,centrallymounted on the studs, so that they will grip the glass withequal force throughout their entire length. Each aw has a longitudinallydove-tail groove 18 extending longitudinally thereof, to receive arubber or other cushion 19, which protects the glass from beingscratched or otherwise damaged by the jaws. Cushion 19 is held fromlongitudinal movement in the groove by a shoulder 2O and bolts 21. Thebolts, however, may be omitted by forcing the cushion into the groovefriction tight. The jaws and handles are locked in closed position by aratchet-bar 22, pivotally secured to handle 1, and a lug containing atooth 23, on handle 2; these parts being on the back of the handles soas not to interfere with a large pane of glass extending above thehandles. By mounting the jaws on the laterally projecting studs, a paneof glass may be gripped without interfering with the enlarged portions 5and 6 of the levers. This is important as a large pane of glass may begripped near its lower edge where it can be more conveniently carried,whereas if the jaws were in alinement with the levers, only the upperedge of the glass could be gripped, as otherwise it would contact withthe enlarged portions 5 and 6, which, of course, would render the tongsuseless as they would be too high to handle.

In carrying a large pane of glass to a window-frame the two verticaledges of said pane are grasped by the jaws ofrtwo pairs f, SSAQ of tongswhich are firmly locked in a closed position by the ratchet-bars 22 andthe lugs 23. Each main handle is then grasped by a man and the glass iscarried to the frame. The lateral vibrations imparted to the handleswhile carrying the glass, will not be transmitted to either the jaws orthe glass on account of the jaws being pivotally mounted on the studs,hence the glass can easily be held in an upright position. When theframe is reached, the glass is readily lifted up into position bygrasping the supplemental handles l0 and ll, which are provided for thaturpose.

Vhile I have shown the preferred form of my invention, I, of course,reserve the right to make such changes in form, proportions, and detailsof construction, as properly fall within the spirit and scope of theappended claims.

Having thus described my invention, what I claim is:-

l. A pair of tongs consisting' of two crossed-levers operably connectedat their crossed portions, means projecting laterally from one side ofthe lower terminals of said levers, and a pair of aws pivotallyanountedupon said means and arranged wholly' at one side of the levers,substantially as shown erally-extending handles on each lever, sub-Vstantially as shown and described.

3. A pair of tongs consisting of two crossed levers operably connectedat their crossed portions, means projecting forwardly from the lowerterminals of said levers, a pair of jaws pivotally-mounted upon saidmeans and arranged wholly at one side of the levers, and means at therear sides of the levers for locking the same, substantially asdescribed.

In testimony whereof I aiix my signature, in the presence of twowitnesses.
